Division 2

In Division 2, the world of metrology rotates around the "electrical triangle" of volt, ohm and ampere - from high-frequency and energy measuring technology to quantum electronics.


Electrical quantities are ubiquitous in metrology. The Electricity Division is charged with the realization and dissemination of the electrical and magnetic units. To this end, the Electricity Division develops precision electromagnetic measurements, which are based on electrical quantum metrology and quantum standards nowadays. Nanotechnology is employed and advanced for the in-house fabrication of superconductor and semiconductor quantum standards. Fundamental studies of quantum effects in condensed matter lay the groundwork for the electrical metrology of the future.

The Electricity Division offers various calibration services (see Calibration and Measurement Capabilities) and advises governmental authorities, standardization organizations, and industry on electrical measurements. Knowledge transfer programs support innovation and economic growth.


The Helmholtz Prize 2018 in the category "Application" was awarded to a research team of the Physikalisch-Technische Bundesanstalt. Dietmar Drung (Division 7), Martin Götz, Eckart Pesel and Hansjörg Scherer (all Division 2) received the prize, which is considered the most prestigious award in the field of metrology, for their groundbreaking improvements in the field of high-precision traceable...

For the first time, measurements performed on systems for air navigation control and surveillance have shown that wind turbines (WT) may impose influences on the signal integrity of such systems. These results were found during a research project coordinated by the Physikalisch-Technische Bundesanstalt (PTB). The measurement instrumentation and methods used up to now have not been able to identify...
